[ technical effect ] it is possible to:

in this configuration, the light from the light source plate provides light to the first, second and even third holes in a "serial" fashion in sequence. The light emitted by the light source plate is fully utilized, so that the requirements on the power of the light source plate and the number of the LED lamp beads are reduced to a certain extent. Furthermore, in general, the overall length of the plurality of sign holes in the lateral direction is greater than the height thereof in the longitudinal direction, and when the light source plate is disposed beside the sign holes, the length thereof is approximately equivalent to the height of the sign holes, so that the length of the light source plate in the lamp structure of the embodiment of the present application is smaller compared to the structure in which the light source plate is disposed at the bottom of the plurality of sign holes, which also simplifies the overall layout/structure in the housing to some extent.

In the prior art, the light source plate arranged at the inner bottom of the shell is used for providing light sources for the sign holes in a parallel mode, different parts of the light source plate mainly provide light sources for one sign hole, after light passes through the sign hole, residual light reaches the bottom of the opposite side of the shell, and the residual light is difficult to be efficiently utilized, so that the light energy utilization rate of the light source plate is lower.

Particularly, under the condition that the light source plate is arranged adjacent to the main marking hole, the hollowed-out parts of the main marking hole are continuously and/or uniformly distributed on the propagation path of the light rays emitted by the light source plate, and on the first section path of the initial light ray propagation, the light energy of the light source plate is fully utilized and converted into a better optical effect which is presented to the outside through the marking hole. When the light passes through the first section path, certain attenuation occurs, and the attenuation is reduced due to the emission through the main mark hole. However, the hole area of the indicator hole located after the first path is also reduced compared with the main indicator hole, so that the rest light can fully lighten the indicator hole after passing through the first path where the main indicator hole is located, and the enough light intensity is maintained. Therefore, the relative positions and structural relations between the light source plate and the plurality of sign holes in the embodiments fully utilize the dimensional relations and characteristics among the plurality of sign holes, so that the light energy emitted by the light source plate can be more fully utilized, and the light energy utilization rate is improved.

In view of the structural characteristics of the emergency sign lamp, in some embodiments of the application, the housing frame is rectangular and comprises a first part frame and a second part frame where short sides are located, relative to the structure that the light source plate is transversely arranged at the bottom of the housing; the first light source plate is arranged in the shell, and the distance between the first light source plate and the first part of frame is smaller than the distance between the first light source plate and the second part of frame; wherein, the shell is only provided with at least one mark hole between the light source plate and the second part of frame; the light-emitting direction of the lamp beads of the first light source plate faces the second part frame. The vertical layout can make the length shorter, and simultaneously, the wiring or the circuit complexity of the space inside the lamp is simplified, and the fault rate is increased, so that the assembly performance of the lamp is improved. Meanwhile, the length of the vertically arranged light source plates is shortened, so that the LED lamp beads distributed on the vertically arranged light source plates can be more densely distributed on the premise of the same quantity, and the light energy density and the light intensity are also larger. In actual use, through vertically laying the light source board, reduce the LED lamp pearl and can reach unified result of use, even, in some cases, can still make each sign hole outwards keep suitable optical effect under the condition of omitting the light guide plate. The light guide plate can be arranged to be in accordance with and correspond to the shape of the marking hole or the outline of the marking hole, so that the material consumption of the light guide plate can be reduced, and even the light guide plate material is omitted, so that the material consumption of the light guide plate is reduced, the complexity of the whole lamp is reduced, and the assemblability of the lamp is improved.

The length of the light source board that the light source board was laid to vertical is less than horizontal light source board length generally, has saved the material of light source board, and in some embodiments, the light source board is vertical to be laid in the side of main mark hole, under the circumstances that reduces the LED lamp pearl, still can reach original effect, the material that has practiced thrift the light source board to a great extent consumes and the photoelectricity of light source board during operation consumes.

Meanwhile, when the vertical light source plate provides light energy for the sign hole, a large space is saved for the shell, the space can facilitate the design of other functions of the shell and the storage of corresponding components and parts, and the utilization rate of the shell is improved.

Furthermore, in some embodiments of the present application, the light source plate is disposed beside the at least one marking hole, and through such vertical arrangement, the light source plate is disposed in the housing, so that water entering the housing of the lamp is prevented from being retained on the light source plate to cause faults, and the waterproof performance of the lamp is improved.

Fig. 1 is a schematic view of a fire emergency sign light according to one embodiment of the utility model. Fig. 2 can be understood as an exploded perspective view of the emergency sign light fixture shown in fig. 1 from a side rear view. FIG. 3 is a flag amplifier in an emergency flag light according to one embodiment of the utility model; fig. 4a-1 to 6 are schematic diagrams illustrating a positional relationship between a light source board and a sign hole in an emergency sign lamp according to an embodiment of the present utility model.

The fire emergency sign lamp, the spatial relationship of the sign piece and the light source board in the related embodiment of the application are described in detail below with reference to the accompanying drawings.

As shown, the fire emergency sign lamp of this embodiment includes:

the housing E1 has at least one index hole, for example, one or more of a main index hole H1, an index hole H2, and the like.

The light source board C0 is arranged beside at least one mark hole. For example, the light source plate C0 may be disposed beside the logo holes H1 and H2 as shown in fig. 2, in other words, in the related embodiment, at least one logo hole is taken as a whole, and the light source plate C0 is located beside the whole in the lateral direction.

Optionally, in the light fixture of some embodiments, the housing E1 has a frame, the frame is rectangular, the rectangular frame has two opposite short sides and two long sides, where the two opposite short sides are a first part of the frame R1 and a second part of the frame R2, for example, the first part of the frame R1 may be located on the right side of the light fixture in the use state, and the second part of the frame R2 may be located on the left side of the light fixture in the use state, as shown in fig. 2.

Optionally, in the luminaire of some embodiments, the light source board may include a plurality of parts, such as a first part of the light source board, a second part of the light source board, etc., or may also be referred to as a first light source board C1, which is arranged within the housing E1. The first part of frame is R1, and the second part of frame R2, wherein, first part of frame R1 is located the left side of lamps and lanterns in the state of using, and the second part of frame is R2 and is located the right side of lamps and lanterns in the state of using, as shown in fig. 4a-1, fig. 4 b.

The distances from the first light source board C1 to the short side frames on both sides of the housing E1 are different, in other words, the first light source board C1 is not located at a middle position in the housing E1.

The distance from the first light source board C1 to the first partial frame R1 is smaller than the distance from the first light source board C1 to the second partial frame R2, i.e. the first light source board C1 is closer to the first partial frame R1 than to the second partial frame R2. The first part frame R1 and the second part frame R2 are respectively positioned at two opposite end parts on the shell E1 and are vertically distributed in the use state of the fire emergency sign lamp. Wherein, the casing E1 only has at least one marking hole between the first light source board C1 and the second part frame R2, including marking hole H1 and marking hole H2. This means that no sign hole is provided between the first light source board C1 and the closer frame R1, neither the main sign hole H1 nor the indicator sign hole H2 or other sign holes are provided on the housing between the light source board C1 and the first partial frame R1. Accordingly, the light emitting direction AA23 of the first light source board C1 faces the second partial frame R2, and the light emitting direction thereof faces away from the first partial frame R1, and the light emitting direction of the first light source board C1 faces the second partial frame R2 far away therefrom.

Optionally, in the luminaire of some embodiments, the light source plate includes a plurality of portions, such as a first light source plate C1, a second light source plate C2. The distance between the second light source plate C2 and the second part frame R2 is smaller than the distance between the second light source plate C2 and the first part frame R1, and the irradiation range of the second light source plate C2 covers a plurality of mark holes, including mark holes H1 and mark holes H2; no mark hole exists between the second light source board C2 and the second part frame R2. For example, the distance L1 between the first light source board C1 and the first portion frame R1 is smaller than the distance L2 between the first light source board C1 and the second portion frame R2, as shown in fig. 4 a-3; optionally, in the lamp of some embodiments, the multiple relationship between the spacing L1 and the spacing L2 is one of 0-10%,15% -30%, 35% -50%, and 60% -99%.

Optionally, in the luminaire of some embodiments, no light source board is provided between the at least one sign hole including H1 and H2, i.e. the light source board C1 in the housing E1 is located only beside the sign hole as a whole, substantially parallel to the two opposite short side frames of the housing E1.

Optionally, in the luminaire of some embodiments, the light source board is a rigid/flexible printed circuit board.

In an emergency sign light of another embodiment of the present application, the at least one sign hole provided in the housing may be implemented as a plurality of sign holes, for example 2 or 3, or more.

Optionally, in the light fixture of some embodiments, the plurality of sign holes includes sign holes H1 and sign holes H2, and the like, and are opened or arranged along the first dimension. The first light source board C1 in the emergency sign lamp shell is located beside the plurality of sign holes H1 and H2 in the first dimension X1, and the light axis/light emitting direction of the light beads of the first light source board C1 spans across the plurality of sign holes H1 and H2 along the first dimension X1.

Optionally, in the luminaire of some embodiments, the plurality of sign holes are formed in the housing along a first dimension, and the light source plate is disposed on an overall side of the plurality of sign holes, and spans the plurality of sign holes inside the housing along the first dimension, and in this structure, light emitted by the light source plate sequentially provides light sources for the first hole, the second hole, and even the third hole in a "serial" manner. The light emitted by the light source plate is fully utilized, so that the requirements on the power of the light source plate and the number of the LED lamp beads are reduced to a certain extent. Furthermore, in general, the overall length of the plurality of sign holes in the lateral direction is greater than the height thereof in the longitudinal direction, and when the light source plate is disposed beside the sign holes, the length thereof is approximately equivalent to the height of the sign holes, so that the length of the light source plate in the lamp structure of the embodiment of the present application is smaller compared to the structure in which the light source plate is disposed at the bottom of the plurality of sign holes, which also simplifies the overall layout/structure in the housing to some extent.

The first dimension may be the lateral direction of the housing E1, or in other words the lateral direction in the use state of the fire emergency sign light, in other words the direction perpendicular to the housing E1/light longitudinal direction.

The first light source board C1 is disposed in the casing E1, and the first light source board C1 is disposed beside the plurality of sign holes H1 and H2 in the first dimension, and no light source board is disposed between the plurality of sign holes. The light axis/light emission direction of the light beads of the first light source plate C1 spans the plurality of sign holes H1 and H2 along a first dimension, i.e. transverse in the use state of the emergency sign light. It will be appreciated that the illumination of the beads of the first light source plate C1 is also unidirectional, illuminating towards the plurality of sign holes H1 and H2, i.e. towards the location or direction in which the plurality of sign holes H1, H2 are located.

Optionally, the sign holes on the luminaire of some embodiments are optical through holes, including a main sign hole H1 and or an indicator sign hole H2. The indication mark holes H2 comprise arrow mark holes and/or character mark holes; the main mark hole H1 is provided with a humanoid running pattern, and the arrow mark hole is a left arrow mark hole or a right arrow mark hole; the text marking holes have a pattern of "EXIT" or "security EXIT" words.

Optionally, the lamp of some embodiments further includes a plurality of markers disposed in the plurality of marker holes, respectively; the light source plate is parallel or basically coplanar with the plurality of marking elements, electronic elements are distributed on the light source plate, and the light source plate is parallel or coplanar with the main marking element and/or the indicating marking element and other marking elements, so that the electronic elements can be conveniently distributed.

The light source plate is vertically strip-shaped and is arranged at the lateral side of the whole of the plurality of marking holes H1 and H2 along the transverse direction;

the indication mark holes H2 comprise arrow mark holes and/or character mark holes;

the light axis/luminous direction of the lamp beads of the light source plate is basically consistent with the indication direction of the arrow mark holes; as shown in fig. 4 a-1.

The plurality of marking elements are in one-to-one correspondence with the plurality of marking holes as shown in fig. 4 a-1; the plurality of markers comprise a main marker 1919 and an arrow marker 1897, which are respectively arranged in the main marker hole H1 and the arrow marker hole H2;

optionally, in the lamp of some embodiments, the arrow mark holes H2 are located at two sides of the main mark hole H1, and are arranged side by side with the main mark hole H1, and the indication directions are opposite, for example, a left indication arrow and a right indication arrow are respectively set at the left side and the right side of the main mark hole H1; alternatively, the arrow mark hole is located on a single side of the main mark hole H1, for example, a right direction indication arrow provided on the right side of the main mark hole H1, or a left direction indication arrow provided on the left side of the main mark hole H1; the arrow mark holes also comprise a first hole and a second hole which are distributed up and down and are opposite in indication direction, as shown in fig. 4 a-3. .

The plurality of sign holes are provided with fire-fighting emergency sign patterns, the main sign hole H1 is provided with a humanoid running pattern, and the arrow sign holes are left arrow sign holes or right arrow sign holes; the character mark holes are provided with patterns of an EXIT or safety EXIT character; for another example, the plurality of marking holes include only a main marking hole H1 and a left arrow marking hole located at the left side of the main marking hole H1; or the plurality of marking holes only comprise the main marking hole H1 and a right arrow marking hole positioned on the right side of the main marking hole H1;

optionally, in the luminaire of some embodiments, the housing E1 has opposite first and second ends R1', R2', opposite third and fourth ends R3', R4'; the length of the first and second ends is less than the length of the third and fourth ends, as shown in fig. 1.

Optionally, in some embodiments, the frame of the housing E1 is a rectangular frame, as shown in fig. 2, and the rectangular frame has two opposite short side frames, that is, a first part frame R1, a second part frame R2, and a first end R1', a second end R2', which have a certain width in a lateral direction. The first end R1 'includes, but is not limited to, a first portion of the frame R1, and the second end R2' includes, but is not limited to, a second portion of the frame R2 (not shown). The first end R1 'and the second end R2' have a certain width and are not limited to the rim or the outer end surface of the rim. For more visual purposes, some embodiments will only take the frame as an example, and the relative positions of the light source plate and the first end R1 'and the second end R2' will be described.

The light source plate is arranged at the first end part and/or the second end part and is basically parallel to the frame corresponding to the first end part or the second end part, and the light emitting direction of the lamp beads of the light source plate faces to the opposite side end part. For example, the light source board C0 is disposed at the first end portion R1', and the irradiation direction of the light source board is toward the second end portion R2' corresponding to the first end portion R1 '; or the light source board C0 is disposed at the second end portion R2 'and irradiates toward the first segment portion R1' corresponding thereto. That is, the light source plate C0 is disposed at the end of the short side of the rectangular housing E1, and the light emitted from the lamp beads spans the internal space of the lamp in the lateral direction X1.

It will be appreciated that the housing E1 is generally rectangular, and the first and second ends, and the first and second partial rims R1 and R2 are each two short sides corresponding to the rectangle. In some special cases, when the casing E1 is irregularly shaped or non-rectangular, the first end and the second end, and the first part of the frame R1, and the second part of the frame R2 correspond to a relatively short frame of the casing E1, or a frame perpendicular to the transverse direction X1.

Optionally, in the light fixture of some embodiments, the first light source board C1 has a vertical bar shape, and a direction of the first light source board C is substantially parallel to the first portion frame R1/the second portion frame R2; alternatively, the strip runs substantially in a direction perpendicular to the first dimension X1. The light bead lighting direction AA23 of the first light source board C1 crosses/spans at least one of the sign holes, including the sign hole H1, the sign hole H2, and faces in opposite directions, as shown in fig. 4 a-1. The shell E1 has no mark hole in the direction deviating from the light emitting direction of the lamp beads of the first light source plate C1. Further, the irradiation range of the first light source board C1 may extend along the first dimension to cover the plurality of flag holes; the light axis/light emitting direction a18 of the light bulb of the first light source board C1 spans the main mark hole H1 toward the indication mark hole H2 at the inner side of the casing E1; or, the light axis/light emitting direction of the light bead of the first light source board C1 spans the main mark hole H1 and the indication mark hole H2 in sequence inside the casing E1.

It can be understood that, as shown in fig. 4a-1, in the case that the first light source board C1 is disposed adjacent to the main sign hole H1, the hollowed-out portion of the main sign hole H1 is relatively continuously and/or uniformly distributed on the propagation path of the light emitted by the light source board C1, and in the first path of the light propagation, the light energy of the light source board is relatively fully utilized, and is converted into a better optical effect that is presented to the outside through the sign hole H1. When the light passes through the first segment path, a certain attenuation occurs, and the attenuation is reduced due to the emission through the main mark hole H1. However, the hole area of the indicator hole located after the first path is also reduced compared with the main indicator hole, so that the remaining light can also fully illuminate the indicator hole H2 after passing through the first path where the main indicator hole is located, so that the light intensity is kept enough. Therefore, the relative positions and structural relations between the light source plate and the plurality of sign holes in the embodiments fully utilize the dimensional relations and characteristics among the plurality of sign holes, so that the light energy emitted by the light source plate can be more fully utilized, and the light energy utilization rate is improved.

Optionally, in the luminaire of some embodiments, the at least one flag hole/holes are main flag holes H1 and/or indicator flag holes H2 distributed in a lateral direction, as shown in fig. 1, 2, and 4 a-1.

The light source board C0 is arranged along the vertical Y1 and is located at a single side of the plurality of sign holes H1 and the sign holes H2, as shown in fig. 2, and of course, the light source board includes a first light source board C1, and the second light source board C2 may also be located at two sides of the plurality of sign holes H1 and H2, as shown in fig. 4 d.

The light source board includes first light source board C1, and second light source board C2 lays in the side in a plurality of sign holes, and C1 lamp pearl luminous direction strides across main sign hole H1 and indication sign hole H2 in proper order. Alternatively, the light emitting direction of the light beads of the light source plate C2 may sequentially cross the indicator hole H2 and the main indicator hole H1, as shown in fig. 4 d.

Optionally, in the light fixture of some embodiments, the number of LED beads on the first/second light source board adjacent to the indicator hole is smaller than the number of LED beads on the second/first light source board adjacent to the main indicator hole, as shown in fig. 4 d.

Optionally, for an emergency sign lamp with a right arrow indication sign pattern, the light source plates C1, C2 are arranged on the left side of the main sign hole H1 and/or the right side of the indication sign hole H2 along the vertical direction Y1; as shown in fig. 4 d.

Alternatively, for the emergency sign lamp with the left arrow indicating sign pattern, the light source board C0 may be vertically disposed on the right side of the main sign hole H1 and/or the left side of the indicating sign hole H2, as shown in fig. 2, where the light source board C0 is vertically disposed on the right side of the main sign hole H1.

The light axis/light emitting direction of the light beads of the light source plate crosses the main mark hole H1 toward the indication mark hole H2 at the inner side of the housing E1.

It can be understood that the light source board is vertically arranged, so that the material of the light source board is saved, when the shell only has the main sign hole, the light source board is vertically arranged at the side of the main sign hole, and the material consumption of the light source board and the photoelectric consumption of the light source board during working are saved to a greater extent.

Meanwhile, when the vertical light source plate provides light energy for the main mark hole, a large space is saved for the shell, the space can facilitate the design of other functions of the shell and the storage of corresponding components and parts, and the utilization rate of the shell is improved.

Optionally, in the luminaire of some embodiments, the light source plate C1 is disposed along the vertical Y1 and is located on a single side or two sides of the at least one sign hole; the at least one marking aperture comprises indicator marking apertures H2 and/or main marking apertures H1, distributed in a transverse direction, the indicator marking apertures H2 being located on one or both sides of the main marking apertures H1, as shown in fig. 4a-1, fig. 4d, fig. 5. In the case where the index hole H2 is located on one side of the main index hole H1, for example, at least one index hole includes only the main index hole H1 and a left-hand arrow index hole located on the left side of the main index hole H1; alternatively, the at least one marking aperture includes only the main marking aperture H1 and a right arrow marking aperture located to the right of the main marking aperture H1, as shown in FIGS. 1, 2, 4a-1, and 4 d. In the case where the index hole H2 is located at both sides of the main index hole H1, for example, the plurality of index holes includes the main index hole H1 and a left-hand arrow index hole located at the left side of the main index hole H1, and a right-hand arrow index hole located at the right side of the main index hole H1, as shown in fig. 5, 6.

Alternatively, in the lamp of some embodiments, as shown in fig. 4a-1, the light source plate C1 is disposed on the left side of the plurality of sign holes H1, H2 along the vertical direction Y1. The H1 mark hole is a main mark hole H1, the H2 mark hole is an arrow mark hole, and the arrow mark hole is a right arrow mark hole. The light source board C1 is arranged in: the main marking hole H1 and the right arrow marking hole are arranged on the left side of the whole, so that the main light source plate C1, the main marking hole H1 and the right arrow marking hole are arranged in sequence from left to right.

The light source panel includes a plurality of LED light beads for providing light energy at the

flag

1919,1897. The irradiation direction of the light source plate is across the main mark hole H1 and the index mark hole H2 in the lateral direction X1 within the housing E1. Note that no sign hole is provided between the light source plate C0 and the left side frame of the case E1.

Optionally, a light guide plate P1 may be further disposed in the housing, where the light guide plate P1 is disposed on the right side of the light source plate, and the light guide plate P1 corresponds to the main mark hole H1 and the indication mark hole H2. In fig. 4a-1, the light guide plate P12 corresponding to the index mark hole H2 is rectangular.

In practical application, the LED lamp beads are not required to be arranged on the corresponding other side towards the side containing the marking holes. It will be appreciated that the above definition applies similarly to C2.

Optionally, in the lamp of some embodiments, the light guide plate P1 is attached to or covered on the inner side of the housing E1; the light guide plate P1 optically covers at least one of the marking holes, including the main marking hole H1 and/or the indication marking hole H2, and is shaped to conform to/correspond to the outline OT1 of the at least one marking hole, e.g., the light guide plate P1 covers the main marking hole H1 and the right arrow indication hole, or the light guide plate P1 covers the main marking hole H1, as shown in fig. 4a-1,4 b. The light guide plate P1 may cover the main mark hole H1 and the left-side arrow indicating hole, or the main mark hole H1 and the left-right arrow indicating hole.

The optical surface of the light guide plate P1 is formed with mark patterns on a plane or protruding, the mark patterns are respectively engaged into the corresponding mark holes, and the mark patterns are distributed with light guide points.

Optionally, in the lamp of some embodiments, the light source board is parallel or substantially coplanar with the light guide plate P1, so as to facilitate arrangement of electronic components on the light source board.

Optionally, in the luminaire of some embodiments, the light guide plate P1 is narrowed on both sides in the longitudinal direction thereof in a direction from the main flag hole H1 to the index flag hole H2; the light guide plate P1 has a height in the vertical direction smaller than a length thereof in the lateral direction. The plurality of marking holes as a whole have a height in the vertical direction smaller than a length thereof in the lateral direction. The height of the light source plate in the vertical direction is smaller than the whole length of the plurality of mark holes along the transverse direction.

Optionally, in the light fixture of some embodiments, the light guide plate P1 includes a plurality of portions P11 and P12 corresponding to the plurality of sign holes H1 and H2, each portion of the light guide plate P1 is arranged side by side along the long side direction of the rectangle, and the sign patterns on each portion of the light guide plate P1 are respectively engaged into the corresponding sign holes; the respective portions of the light guide plate P1 are independent of each other or are integrally connected to each other.

Optionally, in the luminaire of some embodiments, the first portion P11 of the light guide plate P1 optically covers the main flag hole H1, and the second portion P12 of the light guide plate P1 optically covers the indication flag hole H2; as shown in fig. 4a-1, the first portion P11 of the light guide plate P1 optically covers the main marking hole H1, the second portion P12 optically covers the right-hand indication arrow, and the height of the second portion P12 in the longitudinal direction is smaller than the height of the first portion P11 in the longitudinal direction; the first portion is integrally connected to the second portion and is substantially convex in the transverse direction. Wherein the first portion P11 is substantially rectangular and the second portion P12 is trapezoidal or rectangular, as shown in fig. 4a-1 and 4 a-2.

Optionally, in the light fixture of some embodiments, the position of the light guide plate P1 is disposed between the first light source plate C1 (main light source plate) and the second partial frame R2; the light guide plate P1 extends around the sign hole and is optically connected to the first light source plate C1, as shown in fig. 4a-1, fig. 4d, fig. 6, etc. Wherein, the length of the light guide plate P1 or a plurality of mark holes in the vertical direction is smaller than the length thereof in the transverse direction. Since, in general, the length of the first light source board C1 in the longitudinal direction Y1 is approximately equal to the height of the B) main mark hole H1 in the longitudinal direction, the ratio thereof is generally within any one of the following sections:

[0.7，0.8]、

[0.8，0.9]、

[0.9，1]、

[1，1.1]、

[1.1，1.2]、

[1.2，1.3]、

[0.7，1.3]、

[0.8，1.2]、

[0.9，1.1]、

[0.7，1.0]、

[0.8，1.1]、

[0.9,1.2], or

[1，1.3]

The overall length of the plurality of marking openings H1, H2 arranged next to one another in the transverse direction is, however, considerably greater than the height of the plurality of marking openings in the longitudinal direction, i.e. the height of the main marking opening H1 in the longitudinal direction. In view of this, in general, the light source plate C1 has a height in the vertical direction smaller than the entire length of the plurality of sign holes H1, H2 in the lateral direction. The length of the "light source plate disposed on the side along the vertical Y1" in the lamp structure of this embodiment is shorter than the structure in which the light source plate C1' is disposed at the bottom of the plurality of sign holes H1, H2-2 as shown in fig. 8, which also simplifies the structure and overall layout in the housing to some extent.

Optionally, in the lamp of some embodiments, the light source plates C1, C2 are disposed on two sides of the three sign holes H1, H2-2 as a whole, wherein the light guide plate P1 may be considered to be located between the second light source plate C2 and the first portion of the frame R1, and of course, the position of the light guide plate P1 may also be considered to be located between the second light source plate C2 and the first light source plate C1, as shown in fig. 5 and 6; the light guide plate P1 extends around the sign hole and is optically connected to the second light source plate C2, and it can be understood that the first light source plate C1 and the light source plate P1 are also optically connected to each other.

Comparing the relative positional relationship between the marking holes and the light source plate shown in fig. 2 with fig. 5 and 6, the light source plate C0 shown in fig. 2 is closely adjacent to the main marking hole H1, the light emitted by the light source plate C1 is converted into the light effect in the main marking hole, and the residual light can be continuously supplied to the indication marking hole, so that the light energy utilization rate is higher. However, regarding the relative positional relationship between the sign hole and the light source plate shown in fig. 5 and 6, there is no sign hole in the case E1 at the area EE1 above and below the sign hole H2, so that the light emitted from the light source plates C1, C2 is attenuated in the vicinity thereof but is not converted into the light effect in the sign hole, and the waste of light energy is generated to some extent, and when the light passes through the area E1 and is attenuated/scattered to some extent, it reaches the main sign hole H1, and the main sign hole requires more light to make the external optical effect meet the standard due to the larger size. The embodiment of fig. 2 therefore has a higher light energy utilization than the luminaire structures of fig. 5 and 6.

Optionally, in the luminaire of some embodiments, the light guide plate P1 optically covers the plurality of sign holes including sign holes H1, H2 from the inside of the housing E1; the first dimension in some embodiments may be understood in some application scenarios as a lateral direction in the use state of the fire emergency sign luminaire; the second light source plate C2 and the first light source plate C1 are distributed along the vertical direction Y1, are respectively and optically connected to two transversely opposite end parts of the light guide plate P1, and are parallel or basically coplanar with the light guide plate P1; it is noted that the length of the light guide plate P1 in the vertical direction is smaller than the length thereof in the lateral direction, or the length of the plurality of marking holes H1, H2 in the vertical direction is smaller than the entire length of the plurality of marking holes H1, H2 in the lateral direction, as shown in fig. 5, 6, etc.

Optionally, in the lamp of some embodiments, as shown in fig. 4b, the light source plate C1 is vertically disposed on the left side of the main sign hole H1, and no sign hole is formed between the light source plate C1 and the left side frame R1 of the housing E1, and the light guide plate P1 corresponds to the main sign hole H1. The light source board C1 includes a plurality of LED light beads, LE-1, LE-2, LE-3, LE-4, which provide light energy to the position of the marker 1919, and there is no marker hole between the light source board C1 and the frame R1, so that the light emitting directions of the LEDs shown in the figure are directed to a single side of the light source board, i.e. only to the position/direction where the main marker hole H1 is located.

Fig. 4c shows the internal structure of an emergency sign light according to a further embodiment of the present application, which is different from fig. 4b in that the light guide plate P1 corresponding to the main sign hole H1 is not provided in fig. 4c, and when the sign holes are fewer, for example, only the main sign hole H1 is opened on the housing, or the main sign hole H1 and the left direction arrow, or the main sign hole H1 and the right direction arrow, or the single left side arrow, or the single right side arrow are configured, the light energy may be provided to the sign hole where the sign member is located only through the plurality of LED lamp beads of the light source plate, and the light guide plate P1 is not provided.

It can be understood that the light source plate is vertically arranged in the shell, so that the water liquid entering the lamp shell is prevented from being retained on the light source plate to cause faults, and the waterproof performance of the lamp is improved.

Of course, those skilled in the art will also appreciate that: the length of the light source plate positioned at the side of the marking hole is shorter, under the condition that the number of the light beads is the same, the distribution density of the LED light beads on the light source plate is higher, the light energy emitted by the light beads is relatively more concentrated, but not divergent, the light energy is matched with the enclosing of the upper bottom and the lower bottom of the shell to the light, and the illumination intensity is enough to supply the marking piece, so that the lamp has enough optical effect to the outside under the condition that the shell structure with more marking holes, such as the shell is provided with three marking holes, namely a main marking hole H1, a left indicating arrow and a right indicating arrow, or three or more marking holes matched with the main marking hole H1 and the character pattern, can be used for arranging the corresponding light guide plate P1.

It can be understood that the light guide plate can be set to conform to and correspond to the shape of the marking hole or the outline thereof in shape, so that the material consumption of the light guide plate can be reduced, the material consumption of the light guide plate is saved, the use of the light guide plate material is eliminated even in part of the implementation examples, the energy consumption is reduced, the complexity of the whole lamp is reduced, and the assemblability of the lamp is improved.

The optical effect of the luminaire with the light source plate arranged on the side of the sign hole will be described in detail below with reference to the two embodiments shown in fig. 4a-1 and fig. 8. Fig. 4a-1 shows an exploded perspective view of an emergency sign light with a light source board disposed in the housing on the side of the sign hole. As shown in fig. 4a-1, 4 LED lamp beads are distributed on the light source plate C1 arranged at the side of the main mark hole, while 6 LED lamp beads LE-1, LE-2, LE-3, LE-4, LE-5, LE-6 are distributed on the light source plate C1' at the bottom of the housing in fig. 8. Wherein the marking hole H1 is mainly irradiated by both the lamp beads LE-4 and LE-3, and the arrow marking hole H2-1 is mainly irradiated by both the lamp beads LE-5 and LE-6. However, since the length of the light source board C1 shown in fig. 4a-1 is equivalent to the height of the main mark holes in the longitudinal direction, the main mark holes H1 shown in fig. 4a-1 are irradiated by 4 Led beads distributed on the light source board C1, and after passing through the first light propagation path of the area where the main mark holes H1 are located, the light emitted from the 4 Led beads will continue to commonly irradiate the right-hand arrow mark holes H2.

From simulation experiments under certain predetermined conditions, it is known that: under the internal structure of the lamp shown in fig. 4a-1, the light intensity generated at the arrow mark hole H2 is equivalent to the light intensity in the mark hole H2-1 caused by the nearby irradiation of the arrow mark hole H2-1 by arranging 2.3 to 3.1 LED beads at the positions of the LED beads LE-5, LE-6 in fig. 8. Therefore, the light source board layout structure shown in fig. 4a-1 at the side can shorten the length of the light source board and reduce the number of LED lamp beads on the light source board, compared with the lamp structure of the embodiment shown in fig. 8. Or, the light source board that the limit was laid can still obtain the even better optical effect that is equivalent to fig. 8 under the condition that length is shorter, led lamp pearl quantity is less. This allows the luminaire structure shown in fig. 4a-1 to maintain a good optical effect even without the light guide plate in the housing.

Therefore, by adjusting factors such as the vertical side layout of the light source plate, the irradiation direction, etc., the light guide plate P1 can be reduced, for example, the light guide plate P1 corresponding to the arrow mark holes can be narrowed on both sides CC1, CC2 in the longitudinal direction without extending downward any more to form an optical connection with the light source plate at the bottom of the case E1. The structure design makes the light guide plate have smaller size and intensively cover the sign holes, and then the light energy is correspondingly and basically concentrated at the sign holes, thereby efficiently utilizing the light energy of the light source plate. The light guide plate P1 is made of materials, light energy loss is reduced, complexity of the whole lamp is reduced, and assemblability, manufacturability and optical effect of the lamp are improved.

Optionally, in the luminaire of some embodiments, as shown in fig. 4d, the first light source board C1 is disposed on the left side of the plurality of sign holes H1, H2 along the vertical direction Y1. The main mark hole H1 is in a human-shaped running pattern. The marker hole H2 is an arrow marker hole, and an arrow marker Kong Jiantou is directed to the right.

In fig. 4d, the second light source plate C2 is vertically disposed on the right side of the plurality of sign holes. The second light source board C2, the arrow mark hole H2, the main mark hole H1 and the first light source board C1 are arranged from right to left in sequence.

The first light source plate C1 and the second light source plate C2 are respectively in a strip shape and are vertically arranged in the shell E1 and are basically parallel to the first partial frame R1/the second partial frame R2, so that the second light source plate C2 is basically parallel to the first light source plate C1; the light-emitting direction of the light beads crosses/spans the plurality of sign holes to face the first light source board C1, in other words, the light bead emitting direction of the second light source board C2 spans the indication sign hole H2 and the main sign hole H1 in sequence, or spans the indication sign hole H2 to face the main sign hole H1 at the inner side of the housing.

The light source board is arranged vertically, so that the length of the light source board is shorter, meanwhile, the wiring or circuit complexity of the space inside the lamp is simplified, the fault rate is increased, and the assembly performance of the lamp is improved. Meanwhile, as the length of the vertically arranged light source plates is shortened, when the number of the light beads is fixed, the LED light beads distributed on the vertically arranged light source plates can be more densely distributed, and the light energy density and the light intensity are also larger.

In the prior art as shown in fig. 8, the light source plate disposed at the bottom of the housing provides light sources for the sign holes in a parallel manner, and different portions of the light source plate mainly provide light sources for one of the sign holes corresponding to each of the different portions.

Compared with the situation shown in fig. 8, in some embodiments of the present application, the light source plates vertically arranged at the side sides can provide light energy for the plurality of sign holes in a serial manner with greater light energy density, so that the requirements of the emergency sign lamp on the optical effect can be more easily met.

Meanwhile, when the vertical light source plate provides light energy for the main mark hole H1, a large space is saved for the shell, the space can facilitate the design of other functions of the shell and the storage of corresponding components and parts, and the utilization rate of the shell is improved.

It will be appreciated that when the second light source board C1 is disposed on the left side of the main mark hole H1 and the indication mark hole H2, correspondingly, the light axis/light emitting direction AA23 of the light bead of the second light source board C2 spans the main mark hole H1 and the indication mark hole H2, or spans the main mark hole H1 and faces the indication mark hole H2, on the inner side of the casing E1. Optionally, a first light source board C1 may be further disposed on the right sides of the main mark hole H1 and the indication mark hole H2, where the light bead of the first light source board C1 sequentially spans the indication mark hole H2 and the main mark hole H1, or spans the indication mark hole H2, and faces the main mark hole H1, inside the casing E1. Therefore, the light source plates C1 and C2 are arranged on the two sides, the capability of providing light energy for the sign holes is further enhanced, and the optical effect of the lamp on the external appearance is further improved.

Further, the second light source board C2 includes at least one LED light bead, and the number of LED light beads on the second light source board C2 and the number of LED light beads on the first light source board C1 may be the same, as shown in fig. 4d, and the number of LED light beads on the second light source board C2 may also be less than the number of LED light beads on the first light source board C1, or greater than the number of LED light beads on the first light source board C1, and the LED light beads on the first light source board C1 and the second light source board C2 are arranged, and the number of LED light beads are matched to form sufficient irradiation for light energy of the marker. For example, the plurality of LED lamp beads on the first light source board C1 are first group of LED lamp beads, and at least one LED lamp bead on the second light source board C2 is second group of LED lamp beads, and the strip trend of corresponding light source board is laid respectively. The first group of LED lamp beads are vertically distributed on the left side of the main mark hole H1; the second group of LED lamp beads are vertically distributed on the right side of the indication mark hole H2, and the number of the second group of LED lamp beads is smaller than that of the first group of LED lamp beads. Or, the first group of LED lamp beads are vertically distributed on the right side of the main mark hole H1, the second group of LED lamp beads are vertically distributed on the left side of the indication mark hole H2, and the number of the second group of LED lamp beads is smaller than that of the first group of LED lamp beads.

It will be appreciated that in some embodiments, the portion of the light source panel where the first set of LED light beads is located may also be considered as a single light source panel, or "first light source panel" in other embodiments.

As shown in fig. 3, a plurality of flag members 1919, 1897 (exemplified by flag member 1897) are raised on to form a flag pattern Pat23, and the flag pattern Pat23 is raised into the flag holes H1, H2. Since the optical surface of each marker is protruded to form the marker pattern Pat23, a step Ste23 is formed at the periphery of the optical surface of the marker. The mark pattern Pat23 protrudes into the corresponding mark hole H2, and meanwhile, the step bit is clamped with the edge of the corresponding mark hole H2 to form stable mechanical coupling, so that the mountability of the mark piece in the mark hole is improved.

Wherein, no sign hole is arranged between the first light source board C1 and the short frame R1 on the left side of the shell E1. No sign hole is formed between the second light source board C2 and the short frame R2 on the right side of the housing E1, or the housing E1 is not provided with a sign hole in a direction away from the light emitting direction of the light beads of the second light source board C2. Accordingly, the plurality of sign holes as a whole, with no light source board disposed therebetween, as shown in fig. 6.

The light source board C1 is arranged on the left side of the main sign hole H1 and the arrow sign hole, and is a first light source board C1 (main light source board C1), a main sign hole H1, an arrow sign hole and a second light source board C2 from left to right in sequence. The first light source board C1 and the second light source board C2 have substantially the same length.

It will be appreciated that the length of the light source panel may be adjusted according to the illumination requirements of the actual sign hole. The length of the first light source plate C1 is smaller than that of the second light source plate C2, and the irradiation ranges of the first light source plate C1 and the second light source plate C2 are complementary to each other as shown in fig. 6. It should be noted that fig. 6 is only a schematic diagram, and illustrates the situation of light complementation, the specific positions of the light beads do not represent the positions of the light beads in actual use, and in actual use, the positions of the light beads can be adjusted according to the positions of the marking holes and the light requirements, for example, the length of the second light source plate C1 is smaller than that of the first light source plate C2, and the positions of the light beads also change. Or, the length of the first light source plate C1 is greater than that of the second light source plate C2, and the first light source plate C1 and the second light source plate C2 are matched through the length to form complementation in the aspects of width of an irradiation range and irradiation distance. The sum of the lengths of the first light source board C1 and the second light source board C2 may be smaller than the length of the transverse light source board C1' as shown in fig. 8, so that materials are saved for manufacturing the light source board.

Optionally, in the luminaire of some embodiments, the fire emergency luminaire includes a control module integrated on the first light source board C1 and/or the second light source board C2: the LED lamp beads on the first light source plate C1/the second light source plate C2 are independently controlled by the control module and used for providing light sources for the plurality of marking holes including marking holes H1 and marking holes H2 respectively.

Next, taking the positional relationship between the light source plate and the sign hole shown in the embodiment in fig. 8, 9 as an example, the technical effect of the oblique arrangement of the LED beads on the light source plate will be described in detail with reference to fig. 10.

Next, taking the positional relationship between the light source plate C1' and the sign hole shown in the embodiment in fig. 9 as an example, the technical effect of the oblique arrangement of the LED lamp beads on the light source plate will be described in detail with reference to fig. 8, 10. Of course, it should be understood that: although the inclined structure and the optical effect thereof in the drawings are easier to illustrate, the case where the light source board R1 is arranged at the bottom of the housing along the lateral direction is adopted in the related embodiments, however, the inclined arrangement structure of the LED lamp beads on the light source board vertically arranged at the side of the marking hole in the embodiments in other drawings such as fig. 6 also has similar optical effect and will not be repeated.

Analysis of optical effects

Optically, by forming the irradiation regions of the pair of adjacent LED beads under the inclined structure, a more desirable combination of irradiation regions can be obtained for the plurality of LED beads as a whole, the irradiation coverage of the plurality of LED beads can be adjusted, and the shape of the irradiation regions can be optimized, as compared with the arrangement structure of "the LED beads are far apart and the optical axes are substantially parallel" as shown in fig. 8.

This effect is achieved because, to a certain extent, the illumination intensity of the LED lamp beads themselves has the characteristic of being distributed according to angles/radial angles, and referring to fig. 10, it can be assumed for easy understanding that the illumination area of the LED lamp beads is a substantially fan-shaped area having a certain angle, as defined by various broken lines in fig. 8 and 9, the inclined arrangement of the LED lamp beads corresponds to the distribution of the fan-shaped illumination area by rotating and adjusting the LED lamp beads LE-1 as the center, and the characteristic of the inherent distribution shape of the illumination intensity of the LED lamp beads LE-1 is more satisfied, therefore, the splicing and combination of the illumination areas of two LED lamp beads can be well realized under the condition that the distance between the adjacent LED lamp beads LE-1 and LE-2 is more appropriate, thereby, the better illumination area distribution and more uniform light intensity distribution in the internal space of the casing E1 can be formed, and the light energy of a plurality of LED lamp beads can be fully utilized as a whole.

In the scheme shown in fig. 8, the plurality of LED beads LE-1, …, LE-6 are substantially parallel to each other and have no inclination with respect to the vertical Y1 of the lamp, under this arrangement, if the distribution of the irradiation areas of the respective LED beads is adjusted by means of the adjustment of the spacing between the respective LED beads, it is difficult to form a good complement and assembly between the irradiation areas of two adjacent beads, so that the light distribution of two adjacent beads is not uniform enough, for example, it is easier to make the illumination intensity of the space V34 between two beads LE-3, LE-2 in the case E1 insufficient, while if the space V34 between the two beads is reduced by means of reducing the spacing between the beads LE-1 and LE-2, the amount of LED beads on the circuit board R1 will be increased to a large extent (the area of weaker light intensity between the two LED beads), and, for the small-sized marking hole H1-1, the overlapping between the beads LE-1 and LE-2 is not excessive. However, if the interval between the LED light beads is increased to change the irradiation areas of the two adjacent LED light beads LE-1, LE-2, the "irradiation blind area" between the two may be rapidly enlarged along with the increase of the interval between the two, as shown in fig. 8, which results in that the light intensity distribution in the lamp housing E1, especially at the marking hole, is not uniform enough and not optimized enough, and the light energy of the plurality of LED light emitting units cannot be fully utilized, and in some cases, the optical effect of presenting the marking pattern to the outside may be reduced.

As can also be seen by comparing fig. 8 and fig. 9, in the embodiment shown in fig. 7, the irradiation area formed by the 6 vertically inclined LED beads in the inner space of the lamp housing E1 is easier to assemble and splice to adapt to the geometric structure and the dimensional characteristics of the marking holes, for example, the dimension of the middle marking hole H1 is larger than the dimension of the marking holes H2-2 and H2-1 on both sides, corresponding to which, a larger overlap is formed between the beads LE-2 and LE-3 and between the beads LE-4 and LE-5, so that a sufficient light intensity is formed at the marking hole H1. Therefore, the requirement of the inner space of the lamp housing E1 for light intensity distribution is more easily met. Meanwhile, from the whole space, under the condition that all the marking holes H1, H2-2 and H2-1 can obtain enough light energy irradiation and the same light intensity is basically formed in the three marking holes, the light beads are distributed in a small-size space, the larger optical coverage of the space in the shell E1 is obtained, and the light energy utilization efficiency of a plurality of LED light beads is improved.

Further, the marking holes H1, H2 are optionally optical through holes, which means that they are optically through the cover S1, not limited to physical through structures. The optical openings can also be formed in the corresponding locations of the cladding, for example by using transparent materials (or light-transmitting elements, marking elements), but in this case no physical through-holes are formed in the marking holes H1, H2 of the cover S1, but only the transparent, light-transmitting properties are maintained. Popular terms are: the logo aperture remains light transmissive but not necessarily "breathable".

The light guide plate may be an optical cover including a physical direct contact cover or an indirect cover of the sign hole by covering the sign member (if any) in the sign hole, and in this case, the light guide plate is not in direct contact with the inner side of the face cover of the sign lamp but is disposed opposite to the inner side of the face cover at a small distance. The outgoing light on the optical surface of the light guide plate can pass through all positions in the sign hole, thereby presenting a complete sign pattern to the outside.
